This original Tsurumi technology successfully improves the sealing performance of the mechanical seal (shaft seal), which serves as the heart of a submersible pump. The incorporation of Oil Lifter stabilizes and improves the lubricity and cooling action of mechanical seal so that pump operation remains stable even when oil volume decreases.
The Oil Lifter is a lubricating device for the mechanical seal (shaft seal) that serves as the heart of a submersible pump.
The Oil Lifter stabilizes and improves the lubricity and cooling action of the mechanical seal.
It retains the stable sealing effect even if the lubricant falls below the rated volume. The Oil Lifter reduces the number of periodic inspection.
